list of past halo weapons that wont be in H4?

if someone has time, could you give me a list of all the weapons we wont see in H4 from past halo games.
so far all i can think of is:
-smg
-plasma cannon
-spike grenade
-incedinary grenade
-plasma rifle
-?

Grenade launcher
Brute Shot (probably)
Spiker
Mauler
Needle rifle

Plasma cannon is back. They showed it in the first Spartan Ops vid. You might be thinking the Plasma Launcher.

Plasma Repeater
Flamethrower
M6C/SOCOM (odst)
M7S SMG (odst)

Looking at these weapons being cut out makes me sad.

Focus Rifle
Sentinel Beam

EDIT: Also the Missile Launcher

needle riffle sucked anyway as well as the spike grenade, i just wish they put all the weapons from all the games into halo 4, the better the variety makes the game better

-Brute Plasma Rifle (the red one)

I hope they haven’t got rid of the Flamethrower. It’d be much more fun if the flames were shot out much faster than Halo 3’s.

I think they should have brought back the flamethrower and missile pod. Varied it up a bit. Turrets get old after a while.
